Working Principle of BECKHOFF CX2100-0904

The primary function of the BECKHOFF CX2100-0904 is to provide electrical power management for Beckhoff Embedded PC control systems.

During normal operation, the module receives 24 V DC input power and supplies energy to the connected CX CPU module and system expansion components.

The power supply unit distributes regulated power to internal electronics and connected terminal systems. Through the integrated E-bus or K-bus interface, the module supports communication and power supply functions for connected Beckhoff I/O terminals.

When an unexpected power interruption occurs, the integrated capacitive UPS function provides temporary energy storage. This allows the controller system to save important data and execute an orderly shutdown process rather than immediately losing power. :contentReference[oaicite:5]{index=5}

This function is particularly useful in industrial automation systems where data integrity and controlled system behavior are important.
